Abstract
The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements on some of the polymers investigated show, as expected, the existence of bilayered smectic phases SmC2 and SmAd. Taking into account our previous results, an interesting trend in the tilt angle was found that might be related to the difference in alkyl chain substitution.
